Gabby O'Neill presented at the AITPM 'Back to Basics' seminar on the Safe System Approach. The presentation covered South Australia's road fatality data from 2007 to 2016 and examples of road safety treatments implemented, including guard rails, wire rope barriers, shoulder sealing, controlled right turns at signalized intersections, and raised intersection platforms. It concluded that while people make mistakes, road deaths are not inevitable, and using safe system thinking in infrastructure design with elements like lower speeds and dedicated turn lanes can help prevent crashes and reduce injuries.
